Site Description[1] 
Location: The Former Nessen Lamps Site is located at 3200 Jerome Avenue in the Bronx. It is located at the northeast corner of the intersection of Jerome Avenue and Van Cortlandt Avenue East. The site is identified as Block 3323, Lot 36 on the Bronx County Tax Map. Site Features: The site consists of a triangular-shaped, approximately 11,500-square foot property that is fully occupied by an approximately 18,200 sf, 2-story building. The building is currently vacant. Current Zoning: The site is currently zoned C8-2 (commercial district). Until the summer of 2011, the building had been occupied by PS 51X (The Bronx New School), an elementary school serving Kindergarten through 5th grade. Until that time the site had been leased by the New York City School Construction Authority for the school since 1993. Historic Uses: The Site was historically used as a garage (approximately 1928 to 1956); a drug company (1956 to 1965); and by Nessen Lamps Inc. for lamp manufacturing (1971 through 1988). Four 550-gallon buried gasoline tanks were noted at the site between 1945 and 1992 prior to its use as a school. The site was also a Resource Conservation and Recovery Act (RCRA) Non-Generator between 1982 and 1987. Hazardous waste manifests for trichloroethene were filed during this time. Site Geology and Hydrogeology: Bedrock is approximately 20 feet below grade in the vicinity of the site and consists of pre-Cambrian rocks. Groundwater is approximately 12 to 16 feet below grade and is expected to flow in a westerly direction towards Jerome Park Resevoir. 3/8/12-The Department signed the Brownfield Cleanup Agreement for this site.

Site Environmental Assessment
Nature and Extent of Contamination: Soil: Volatile organic compounds (VOCs) have been detected in on-site soil samples at concentrations exceeding standards, criteria, and guidance values. Contaminants of primary concern are chlorinated solvents. Although detected site-wide, concentrations exceed Unrestricted Use Soil Cleanup Objectives (UUSCOs) in only two soil borings. In these locations trichloroethene (TCE) was detected at concentrations of 43 parts per million (ppm) and 3.5 ppm (UUSCO is 0.47 ppm). Some petroleum-related compounds have also been detected: ethylbenzene was detected at 9.8 ppm (UUSCO is 1 ppm); toluene at 1.6 ppm (UUSCO is 0.7 ppm); and total xylenes at 91 ppm (UUSCO is 0.26). Contamination at these elevated levels was from the depth range of 6 to 7 feet below surface grade. Contaminants were detected at lesser concentrations in both shallower and deeper soil samples. Groundwater: To date, only one groundwater sample has been obtained due to shallow refusal. Tetrachloroethene (PCE) and TCE were detected in the sample at very low concentrations (below standards, criteria and guidance). Additional groundwater sampling is required and will be performed during the Remedial Investigation. Soil vapor and indoor air: Indoor air sampling was performed in January and April of 2011. TCE was detected in all samples, as high as 310 micrograms per cubic meter (ug/m3) during the April sampling event. During an enhanced building ventilation study conducted in May 2011, indoor air sampling detected TCE at a maximum concentration of 607 ug/m3 in the partial basement. Sub-slab soil vapor samples collected in March (without concurrent indoor air samples) detected TCE at a maximum concentration of 53,300 ug/m3. Subsequent sampling in April, which coincided with concurrent indoor air samples, detected maximum sub-slab concentrations of 31,000 ug/m3. Significant threat: The Site presents a significant threat to public health due to the occurrence of soil vapor intrusion in the on-site building and possible occurrence in off-site buildings, and the resulting potential for human exposure to trichloroethylene (TCE) in indoor air.

Site Health Assessment
Direct contact with contaminants in the soil is unlikely because the site is covered with buildings and pavement. People are not drinking the contaminated groundwater because the area is served by a public water supply that is not affected by this contamination. Volatile organic compounds in the groundwater or soil may move into the soil vapor (air spaces within the soil), which in turn may move into overlying buildings and affect the indoor air quality. This process, which is similar to the movement of radon gas from the subsurface into the indoor air of buildings, is referred to as soil vapor intrusion. Soil vapor intrusion sampling identified impacts in indoor air quality in the on-site building. Although the building is currently unoccupied, the potential exists for people to inhale site contaminants in indoor air due to soil vapor intrusion in any future on-site building development and/or occupancy. The potential for off-site impacts have not yet been evaluated.
